Con-dem ministers claimed today that they will lift thousands of people out of fuel poverty with a scheme to make homes more energy efficient.
Deputy Prime Minister Nick Clegg claimed the government's new "green deal" would cut household fuel bills and create sustainable jobs.
Under the scheme, homeowners can pay to insulate their houses with a loan from a new not-for-profit Green Deal Finance Company.
But fuel poverty campaigners said the Bill would not stop energy prices rising.
Ed Matthews from Energy Bill Revolution said the government should use money from the carbon tax to pay for home insulations.
Other government plans to rely heavily on ever more expensive gas and put off decisions on renewable energy are set to add to household power bills.
And its welfare cuts are set to drastically increase the number of people in fuel poverty, where they have to spend more than a tenth of their income on heating.
